The AMPTS II is a well engineered analytical device developed for on-line measurements of ultra low bio-methane flows produced from the anaerobic digestion of any biological degradable substrate at laboratory scale.

The AMPTS II follows the same analysing principles as conventional methane potential tests, which make the results fully comparable with common methods. However, with the AMPTS II both the gas volume measurements and data logging are fully automatic during the long incubation period and experimental data is calculated and generated into a standard data sheet. This in turn significantly reduces the time and labour demand for carrying out the analysis and data calculations.

The high quality of the data obtained from the AMPTS II can be used to extract kinetic information of the degradation process, which in turn provides for a much better understanding of the dynamic degradation behaviour of a specific substrate.

The AMPTS II provides the following advantages:

• Automated analytical procedure reducing work load
• User friendly interface for experiment setup, real-time data display and analysis overview
• On-line and real-time data logging of total biomethane production and flow rate
• Automatic real-time pressure and temperature compensation for volume measurements
• Real-time gas flow and volume normalisation
• Algorithm option to avoid an overestimation of gas volume and flow (which may be induced by the flash gas during experimental setup)
• Possibility of multiplexing, allowing for simultaneous batch analysis at different startup times
• High quality data for extracting process kinetic information
• Standalone instrument with embedded data acquisition and web server for remote access
• Low and easy maintenance
• One of the most cost competitive solutions on the market today

The AMPTS II allows users to more easily determine the optimal retention time and substrate mix in order to maximise the utilisation of biogas plants. This in turn will translate into a higher volume of gas produced, allowing for higher profits.
